Set up footer
WoodMart theme allows creating footer of different layouts and colors In Theme Options -> Footer some predefined variants of columns structure.
For example: if you set the footer layout to “Three Columns” you will find 3 widget areas in Appearance -> Widgets so you can add any widgets here and will see them in 3 equal columns.
Footer with HTML block
The other way is to add HTML Block to the footer widget area. To do this, you need to go to Theme Settings -> Footer and select the “HTML Block” as the Footer Content option. Then you will see the dropdown with all the existing HTML Blocks or create a new one. You can create this block using all the elements and layouts of the WPBakery Page Builder plugin or Elementor in HTML Blocks -> Add New.
